Serial port connection

Use the 9-pin RS-232 cable that is shipped with the JTAGICE mkII. Connect the male cable connector to the JTAGICE mkII and the female connector to the host PC. The communication runs at default 19200 bps (maximum 115200), no parity, 8 data-bits, 1 stop bit, (N81) and with hardware handshake (RTS/CTS). If you use another cable than the one shipped with the emulator, make sure all required pins are connected.

AVR Studio can not force control over a COM port. If other equipment or software drivers have control of the COM port (eg. IrDA, PDA or a terminal like HyperTerminal) communication with the JTAGICE mkII will fail. Make sure that no other software has control of the COM port where the JTAGICE mkII is connected.

If the JTAGICE mkII is connected to a COM port other than ports COM1 through COM4, AVR Studio must be configured to scan more ports than the default (4) ports. In AVR Studio, open the Options dialog from the Tools menu, and increase the value of the field entitled "Number of COM-ports to try".
